I have a basic fps engine going at the mo but cant seem to make "collectables" is it possble to like leave a sprite near the floor(medipak) and make the player pick it up as he goes over it? being trying but best i got was that the player got stuck next to it (sliding).

And whats the best way to create windows in a building any ideas, i have cs4 but i prefer maplet.

any help would be appreciated.

thanks

Check out the EntityCollided command in the helpfile.
Something like this:

If CountCollisions ( player)
  entity = EntityCollided ( player,medipak )
     If entity
	make something with your medipak
     EndIf
EndIf

Must be doing something wrong still wont work, the sliding collision works on it.

Collisions cause a collision reaction to occur. According to your example, this is probably not what you want.

I think what you are looking for is the EntityDistance or LinePick commands...

Maybe you can post some of your code to look it over.

Simply check Entitydistance from player to item - don't use collsion with the item.
example given:
Le's assume you have an array of medipack meshes...

...
for i=0 to num_medi-1
 if medipack(i)<>0
  if entitydistance(player,medipack(i))<mindist# then
   health=health+100
   freeentity medipack(i)
   medipack(i)=0
  endif
 endif
next

To prevent pickin things trough walls you may add a entityvisible check after the Distance check. To make Entitysisible work, you need to set the right entitypickmode for the entities. eg entitypickmode medipack(i),2 after loading the mesh.

Thanks chaps entitydistance works a treat.

With all my collectables (medikits,ammo etc..) whats the best method of placing these items in my level i use maplet to build the maps, it would take ages getting the coords for them and typing it into blitz?

any ideas

for i=0 to num_medi-1
if medipack(i)<>0
if entitydistance(player,medipack(i))<mindist# then
health=health+100
freeentity medipack(i)
medipack(i)=0
endif
endif
next

With this code how do i check to see if the entity exsists before i delete it?
